Mix fate and fashion and you get the birth of the Birkin. The Birkin bag came about at an unlikely time. On a flight to London, Jane Birkin inspired Jean-Louis Dumas (then Hermes chairman) to create the ultimate carryall bag. Its release in 1984 changed the luxury game. With every piece dressed in rich seasonal colors, signature hardware and luxe textiles, Hermes upholds the highest standards of craftsmanship. Today, with their ever-growing value, Birkin bags continue to be one of the best accessories to buy for a sound investment. Birkin bag sizes from smallest to largest include 25, 30, 35 and 40.
